CONSTRUCTION OF REENFOBCED BAKIN PAIN S.

Application filed April 8,

This invention relates to pans used for baking'bread, cake and similararticles and is employed ordinarily by wholesale bakeries, althoughobviously the same construction may be used for domestic cookingpurposes, or for other applications some of which are mentioned herein.

The object of-this invention is to provide a strong, light, durable andsimplel cleaning and have other obvious advantages which will be setforthrln the specification, claims and drawing.

Referring to thefirawing: Figure I shows a plan view of a set of threepans attached together in a unit and embodying the features of myinvention; Figure II shows a side elevation partly in section of the setof three pans 1;

Figure III shows in perspective a corner of one of the end pans, showingin more detail some features of my invention;

Figure IV shows a section through a portion of the corner of the panillustrated in Figure III, Figure IV is taken on section line XX;

Figure V shows a section taken on line Y Y of Figure III. a

This invention refers particularly to baking pans which are drawn in aseamless manner withoutfold or joint and from a single sheet of tinplate.

Referring to the drawing;

(1) represents a set of pans composedof individual units (2, 3 and 4).Each of the individual pans is formed with a horizontal top deckportion, indicated as (5). The edges of the deck portion (5) are bentdownward as indicated at (6) around the reenforcing strap member (7)which serves to unite t e pans into a single set. Edge (6) is foldedaround the lower portion of stra member. (7 and upward as indicated atStrap member (7 may be made from a,

rectangular bar or made of any other desired consistent cross-section.At the corners of the set of pans indicated for purposes of illustrationby (9), the strap member (7) is bent around a radius, preferably ofrelatively large dimension to give a smooth gradual bend. A triangularpor- 1927. Serial No. 182,067.

tion of the strap (7) indicated by (10) is exposed at each corner. Thisis shown clearly in Figure III and represents the division between theadjacent side and end of the set. customary to leave the sharp edge ofthe tin plate exposed at this point. This prc-.

viou-s practice offers some difliculties in that the sharp edge terms aprojection on which the bakers or those handling the pans are likely tocatch or tear their hand. Such a joint, also presents a crevice in whichdough, grease or impurities may collect or decay. One of the features ofthe set of pans which I have invented, is the freedom from crevices ofthe kind described and the elimination of opportunity for bakers orthose using the pans to tear their hand.

I have avoided the condition incidental to the sharp edges at the cornerof the pans by the construction shown and described in thisspecification. I provide a groove or indentation (11) running along theedge of the sheet metal which is exposed at the corner portion (10) ofthe set of pans. The edge of the tin plate is then turned downward andinward into the groove (11) thus entirely concealing the sharp edge. Themetal of the strap is then raised outward and downward as shown at (10)for-min a surface which may be in any desire plane, but which I preferto arrange so that it will lie in substantially the same plane as theouter surface of the tin plate (6) which is bent around strap (7).

This construction gives a superior set of pans and provides manyadvantages as set forth.

Forpurposes of further reenforcing the set I provide means as indicatedby strip (12) underneath adjacent edges (13 and 14) of adjacent pans.Strip (12 may be spot welded or seamed to edges (13 and 14) forming astrong and rigid joint and uniting the group of pans into a single set.

It will be apparent from considering the drawings, and specificationsthat I do not wish to be restricted to the exact description iven orshown, but wish my invention be interpreted in the spirit of thedisclosure and the present state of the art. Obvious modifications maybe made inthe details without departing from the spirit of thisinvention.

Having now fully described my invention,

In previous pans, it has been.

inc

.-what I claim as new and wish to secure by Letters Patent in the UnitedStates, is as follows:

1. A series of reenforced baking pans 5 united into a set b a strappingmember,

said strapping mem er surrounding the upper edges of said set andprovided with depressions near the corners, the edges of the pans ofsaid set in contact with said strapping member being formed over saidstraping member, and 30 arranged that the adacent edges of saidpans-Which are formed over-said trapping member are bent into saiddepressions.

2. In a set of reenforced baking pans a strapping member havingtransverse depressions adjacent to the corners of said set, the edges ofa portion of the sides of the an in contact with said strapping member 2eing bent to engage with sand transverse depressions.

3. A set of baking pans, united together by a strapping member havingtransverse depressions adjacent the corners of said sets, the sides ofsaid pans being extended about said strapping member, said depressionsserving to receive the rolled-overraw edges of the sides of said pans incontact withsaid strapping member. 1

4. In a set of baking pans a strapping member serving to unite theindividual pans together, and having transverse depiessions near thecorners of said set.

5. A strapping member serving to unite a series of pans into a set, theouter face of said strapping member having depressions adjacent thecorners of said set, the portion of said strapping member surrounded bysaid depressions being raised above the normal level of the surroundingadjacent surface of said strapping member.-
